Meta Tech Podcast

Brought to you by Meta. In addition to remaining active in the open source community and conference circuit, this podcast offers another channel that allows us to highlight the technical work of our engineers who will discuss everything from low-level frameworks to end-user features. Throughout the podcast, Meta engineer Pascal Hartig (@passy) will interview developers in the company.

    How to Build a Mixed Reality Headset

    How do you build your own mixed reality headset from sketch to scale? That's exactly what Alfred Jones, VP of hardware engineering at Meta Reality Labs, discussed with host Pascal. From choosing the right display technology, battery, thermal budget and of course hitting the right price point. How he manages to not fall victim to choice paralysis and so much more in episode 68.

  2. Measuring Developer Productivity with Diff Authoring Time

    Measuring Developer Productivity with Diff Authoring Time

    At Meta, engineers are our biggest asset which is why we have an entire org tasked with making them as productive as possible. But how do you know if your projects for improving developer experience are actually successful? For any other product, you would run an A/B test but that requires metrics and how do you measure developer productivity? Sarita and Moritz have been working on exactly that with Diff Authoring Time which measures how long it took to submit a change to our codebase. Host Pascal talks to them about the way this is implemented, the challenges and abilities this unlocks. Got feedback?

    Inside Bento - Serverless Jupyter Notebooks at Meta

    Bento is Meta’s internal distribution of Jupyter Notebooks, an open-source web-based computing platform. Host Pascal is joined by Steve who worked with his team on building many features on top of Jupyter, including scheduled notebooks, sharing with colleagues and running notebooks without a remote server component by leveraging Webassembly in the browser.

    Getting Ready for Post-Quantum Cryptography

    We don’t know when but at some point in the future we will face what researchers call a "Quantum Apocalypse". This is when quantum computers will be able to break many of our existing encryption algorithms. To keep Meta’a users safe even from attacks that don’t even exist today, Sheran and Rafael are working on post-quantum-ready encryption. Tune in to learn about the various challenges and trade offs that this work brings with it.   Got feedback?

    Caddy - Building the next generation of CAD software for Mixed Reality

    After sitting in one too many Zoom meetings looking at flat images of 3D models, mechanical engineers Ed, Jason, Fan, and Raghavan decided that they could do better, taught themselves how to code and started to build Caddy - a CAD app for mixed reality.

    The key to a happy Rust/C++ relationship

    Aida was part of one of the first Rust teams here at Meta. One of the biggest challenges was interacting with the large amount of existing C++. With the release of cxx, safe interop between C++ and even async Rust has become a lot easier. Got feedback?

    Building Threads for Web

    The basic version of Threads for web was built in just under three months by two engineers, mirroring the nimble engineering practices we talked about on this podcast before when it came to launching Threads for Android and iOS. In this episode, Pascal is joined by Ally and Kevin, two engineers on the Threads Web team. They talk about how shared infrastructure with other Meta web properties allows them to move fast and how they manage to balance the need to ship new features with the desire to craft delightful experiences for their users.  Got feedback?

    Image Quality Improvements at Scale

    Every day, trillions of image download requests are made from Meta’s family of apps. Zuzanna works on the Media Platform Team that owns the entire flow from serving images from the CDN to displaying the pixels on your phone. One of the project she and her team recently worked on was rolling out HDR images to Instagram and Threads and in this episode’s interview, Zuzanna tells show host Pascal how they partnered with large phone manufacturers to develop and roll out the new feature.
